Changing out the footwell lights

Looks like more than a resistor in circuit too.

 

It's amazing you even cracked that thing. I couldn't figure it out.
Is the color temp still amber? Are you looking to change to white? If so, I may have an easier solution for you.

 

There's a thread in the Gen3 main forum where a guy found a Lexus part, same part, but with a white LED. I think it was from a ES350.

I see you posted in that thread.. so are you trying to do something different than just white LEDs?

 

Ive been trying to find one with a blue led but no luck..

 

On the sixth and last photo, the electronic component in the center next to the LED is a diode. A diode is used to keep the electricity going in one direction - this means the LED is a uni-directional LED and is suppose to get its electricity in one direction ( if that is not obvious by now).

The electronic component to the left of the diode is a resistor which lower the current level of the electricity before it passes through the LED. The bands on the resistor white-brown-brown-gold describe its rating <band1><band2> x 10 ^ <band3> ohms with an error accuracy of <band4>[1] The color scheme for the first three bands is describe by an old engineers mneumonic device.

bad = black = 0
boys = brown = 1
rape = red = 2
our = orange =3
young = yellow =4
girls = green = 5
but = blue =6
violet = violet/purple = 7
gives = grey =8
willingly = white = 9

the last band, band4 is described the tolerance/error of the resistance
with the most common designations as follows:
<no band> =20% error tolerance
silver = 10% error tolerance
gold =5% error tolerance

for example the resistor band in your photo is white brown brown gold

91 x 10^1 ohms @5% error = 910 ohms @5% tolerance.

It's likely that the wiring/current goes on a simple serial path the positive prong/lead - resistor - diode - LED - ground/negative prong/lead. Manufacturing wise I would guess that the ground lead of the diode and a lead from the negative prong are threaded into the metal casing up through the LED housing and through the LED light view port, then the leads are soldered/connected to the LED, then finally the LED is pushed down into light view port. To take the LED - you would poke a screwdriver/thin blade like tool and crowbar/lever/pop the LED out from its viewport opening.

hope this helps

Did anyone crack this nut...? I too would like to get some blue LED's and use the factory mount setup.

Thanks,
Mark

 

I order these last night... I'll tell you how it goes.
